Once you are done working on your project you can **deactivate** the virtual environment.

<div class="termy">

```console
$ deactivate
```

</div>

This way, when you run `python` it won't try to run it from that virtual environment with the packages installed there.

## Ready to Work { #ready-to-work }

Now you're ready to start working on your project.

I will show you some of the main concepts you should probably keep in mind when deploying a **FastAPI** application (although most of it applies to any other type of web application).
